ESP32 CAM How to Take a JPG with Flash ON

Configuration
1

Hi,

I have a ESP32 Cam working to just stream video, I want to be able to Trigger from an automation to do the following:

Turn onboard Flash Light ON
Take a still JPG and display in Lovelace
Turn onboard Flash Light OFF

Can anyone give me pointers where to start with this?
Below is my ESPHOME code

From what I have read I need to add the following to esphome esp32cam yaml:

output:
  - platform: gpio
    pin: GPIO4
    id: gpio_4 

light:
  - platform: binary
    output: gpio_4
    name: flashlight

But when I do this I get an error
light.gpio platform not found…?

Any help appreciated…

I have found if I change this

light:
  - platform: binary
    output: gpio_4
    name: flashlight

to this it works, I can turn the flash On & OFF

switch:        
  - platform: gpio
    name: "Flashlight"
    pin: GPIO4

Now just to find out how to take a still and display

Hey,

I followed your intrusions and added “Light” to my esp32.yaml and a switch for the light showed up in HA.
I didn’t need to change “Light” to “switch”.
